ACleaner

ACleaner is a safe and easy-to-use privacy protection tool, that allows you to erase common Internet and computing tracks, including browser cache, cookies, visited websites, typed URLs, recent documents, index.dat files and more.

You can also easily erase the tracks of up to 100 popular applications. It also includes an option to overwrite deleted data multiple times, so it cannot be easily recovered. The cookie cleaning feature allows you to specify which cookies to keep, so that you don't erase your important login cookies. You also can schedule automatic erasing for any time you like and use boss key to hide all browser windows in one quick keystroke!

In addition, the program comes with a registry scanner to optimize your system registry by finding and removing errors and invalid entries. After fixing the invalid entries, your system will be more stable and run faster. For maximum safety, ACleaner will make a backup of the repaired entries. You will be able to restore any changes made using the software by choosing Restore registry backup.
